OOK RX click

OOK RX click is a wireless receiver that operates at the frequency of 433MHz (sub-GHz). This device allows realization of a simple, low-speed wireless ad hoc communication network between a receiver and compatible transmitter.

Click library

Software Support

We provide a library for the OOKRX Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for OOKRX Click driver.

Examples Description

This example showcases how to initialize and use the OOK RX click. The click decrypts information

embedded in a 433 MHz frequency radio signal. In order for the OOK communication to work a receiver click needs to be used. OOK TX plays that role - it encrypts, embeds and sends the data.

The demo application is composed of two sections :

Application Init

This function initializes and configures the logger and click modules.

{
log_cfg_t log_cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info(&logger, "---- Application Init ----");
// Click initialization.
ookrx_cfg_setup( &cfg );
OOKRX_MAP_MIKROBUS( cfg, MIKROBUS_1 );
ookrx_init( &ookrx, &cfg );
Delay_ms( 100 );
}

Application Task

This function waits for the transmitter to send the data and then reads and displays it in

the console using the UART communication.

{
uint8_t received_package[ 1 ];
if ( ! ( ookrx_receive_data( &ookrx, 0xCE35, &received_package, 1 ) ) )
{
log_printf( &logger, " * Received packet: %d * \r\n", received_package[ 0 ] );
}
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
